badger

I captured this badger (Meles meles) during a heavy storm on my Redleaf RD1000 game camera. The previous badger spent a good while licking the camera but this one first hides and then runs off when it detects it. I’ve noticed from experience that members of the Mustelidae family, for example badgers, martens and weasels, can detect or even see infrared. If they can, then what other creatures can also? Perhaps an ultraviolet trail cam would be more effective?
